Engineering Contradiction Analysis
1Reliability
If the detecting system operates continuously with high power to ensure accurate detection, then the detection reliability is improved, but the overall power consumption of the vehicle increases
Solution Approach 1:
The patent applies dynamics by making the power consumption of the detecting system adjustable rather than fixed. The controlling circuit dynamically changes the power consumption level based on predicted vehicle states (speed and acceleration), allowing the system to adapt between high reliability mode and energy-saving mode according to actual driving conditions
Solution Approach 2:
The patent changes the power consumption parameter of the detecting system based on predicted vehicle states. By using positioning and inertia detecting circuits to predict speed and acceleration, the system adjusts the power consumption parameter of transmitting and receiving circuits to optimize the balance between detection reliability and energy efficiency
2Use of energy by moving object
If the detecting system reduces power consumption to save energy, then the overall power consumption decreases, but the detection accuracy and reliability may be compromised
Solution Approach 1:
The patent uses positioning and inertia detecting circuits to predict future vehicle speed and acceleration states before actually needing to adjust the detecting system's power consumption. This preliminary prediction allows the system to proactively optimize power usage while maintaining detection reliability when needed
Solution Approach 2:
The system implements feedback by using the predicted vehicle states (from positioning and inertia detecting circuits) to control the power consumption of the detecting system. This closed-loop control ensures that detection reliability is maintained by adjusting power consumption based on actual driving conditions
